7 Claims. (Cl. 20-53) My invention relates to a pivotally mounted and laterally shiftable window sash and more particularly to a window sash mounted in the grid of a facade of a building and in which the sash is so pivoted that it may be swung through an angle of three hundred and sixty degrees.

One of the principal objects of the invention is to provide a window in which the sash may be swung inside out, so that both side faces of the window may be readily cleaned and serviced from inside the building and still maintain the window wind and water tight in its closed position.

Another object of the invention isto provide a window in which the pivotal axis of the sash may be shifted with respect to the sides of the opening in the grid of the facade in which the window is mounted.

A still further object of the invention is to provide a window which may be cleaned and repaired on both side faces without the use of scalfolding.

A further object of this invention is to provide a window with a slidable sealing means at both its top and its bottom to seal the joints between the top and bottom edges of the window and the grid.

Another object of this invention is to eliminate the necessity of a window frame and to close and/or seal the window sash against the grid of the facade of the building.

Still another object of this invention is to provi de a Window with a pivoted sash so mounted that it may be opened by first shifting its pivots laterally outwardly from the grid until the side edges of the sash clear the jamb portions on the grid, after which the sash may be rotated on its pivots to the desired positions.

Other objects of the invention will appear hereinafter throughout the specification.

Referring to the drawings:

Patented May 8, 1956 2 arrangement which connects the sash to the sill and allows the sash to move laterally outwardly from the grid structure which serves as a window frame;

Figure 8 is a horizontal section on the line 8-8 of Figure 7 showing the top side of a portion of the lower link arrangement;

Figure 9' is a vertical section on the line 99 of Figure 7 showing the link and pivot connection between the sash and its sill.

Referring to the drawings, 1 represents an opening in the grid 2 of a facade of a building in which a window sash 3 is pivotally mounted and laterally shiftable by means of two pairs of links at both the top and the bottom of the opening 1. Since the link arrangement at the sill 4 and at the head 5 of the opening are the same, except that they are reversed, only one will be described. Each link arrangement comprises a first pair of links 6 and 7 pivoted together at one end and to the sill 4 by a pivot 8, and a second pair 9 and 10 pivoted to the other ends of the first pair by the pivots 11 and 12, and to the lower edge of the sash 3 by the pivot 13. The pivot 13 is located'midway between the side edges of the sash, and the pivots 11 and 12 are located approximately midway between the ends of the links 9 and 10.

In the closed position of the sash it engages against the jamb portions 14 at the sides of the opening 1, and when it is desired to open the window the sash is pushed outwardly to the position of Figure 2 after which it may be swung on its pivots 13 to the position of Figure ,3

from which position it may be swung in a counterclockwise direction back to the position of Figure 2 but with the side faces reversed. The window may now be closed by pushing the sash inwardly to engage the jamb portions 14 of the opening.

When the sash 3 has been brought to its position against the jamb portions 14 it may be sealed at the top and bottom by slidable weather bars. These bars are of the same construction and operate in the same way but as clearly shown in Figure 6 their positions are reversed. Each bar comprises a channel section 15 of generally H-shape in cross section which extends from one side of the windowto the other. An operating member 16 extends from one side of the bar so that the bar may be slid readily to and from its sealing position. One of the U-portions of the H-section is providedwith a sealing member 17 which seals against the adjacent edge of the window sash when the window is in its closed position. These bars are mounted to slide between a sealing member 18 carried by the head portion 5 and the sill portion 4 of the grid, and the sash.

The jamb portions 14 of the opening 1 are each provided with a pair of spaced parallel sealing elements 19 which engage and seal the sash when the window is closed as shown in Figure 5.

As shown in Figures 1, 2, 3, 5 and 6, the grid 2 is of generally hollow channel form in cross section but any other suitable form of cross section may be used. Also, Figures 1, 2, 3 and 5 show fins 20 projecting outwardly from the grid structure but such fins are not necessary in the operation of this window.

Spandrel sections 21 are shown in certain of the grid openings adjacent the window but it will be understood that some or all of these sections could be replaced by windows, if desired. 7

A floor 22 and a window stool 23 are shown in Figure 6 but they are no part of this invention and do not in any way affect the operation of the window.

The term facade used in this application is intended to cover any frame, panel, building face unit, or other structure that may be used to mount a window and/or While the improved window disclosed herein is shown and described as having its sash mounted on vertical pivots, it is apparent that it could be mounted on horizontally disposed pivots, if desired. Moreover, while the improved window disclosed herein is shown and described as having a sash mounted so as to pivot outside, it is apparent that it could be mounted so as to pivot inside of the building upon which it is mounted.

As shown in Figures 6, 7, 8 and 9, felt strips 24 are mounted in the sides of the links 9 and 10 adjacent the top and bottom edges of the sash. These strips supplement the sealing members 17 carried by the retractible weather bars to seal the joints at the top and bottom of the sash.

The free ends of the links 9 and 10 bear on the sill 4 and the head 5 of the opening in the grid and serve to stabilize the sash in its movements to and from a closed position.

A stop screw is adjustably mounted in the end of each of the links 6 adjacent the pivot 8 and projects slightly beyond said end to engage a flattened portion 26 on the adjacent end of the link 7 to limit counterclockwise movement of the link 6 with respect to the link 7 as the sash is moved outwardly to the position of Figure 2.

Plates 27 may be used to cover the outside faces on the links when the window is in its closed position, as shown in Figure 6, if desired.

While the window sash has been illustrated in Figure 3 as being swung in a counterclockwise direction as it is opened, it will be understood that it could be moved in a clockwise direction equally as well.

The operation of the window as illustrated in the drawing will now be described.

Figure 1 shows the window closed and with the sash resting against the jamb portions 14 and all of the links 2 at both the upper and lower edges of the window disposed in the plane of the sash 3. To open the window the sash is moved outwardly to about the position of Figure 2 after which it may be rotated on its pivots 13 in a counterclockwise direction to the position of Figure 3 and then to the position of Figure 2. From this position, the sash may be pushed back to the closed position against the jamb portions, the link arrangements in the meantime being collapsed and brought into registry with the upper and lower edges of the sash. It will be understood that the weather bars 15 must be slid out of engagement with the sash before the opening movement can be begun. After the window is closed, these bars may be restored to their sealing positions.

The above description and drawings disclose a single embodiment of the invention, and specific language has been employed in describing the several figures. It will, nevertheless, be understood that no limitations of the scope of the invention are thereby contemplated, and that various alterations and modifications may be made such as would occur to one skilled in the art to which the invention relates.
